## Abstract

An electric wheel, a remote controller, a vehicle using the electric wheel, and a method for driving a vehicle are disclosed. The electric wheel include a fixed wheel hub, a rotary wheel hub, a tire, a driving motor, and a battery and control unit. The fixed wheel hub may be connected with a vehicle shaft. The rotary wheel hub is mounted on the fixed wheel hub, with an accommodating cavity defined therebetween. The tire is attached around the rotary wheel hub. The driving motor is received in the accommodating cavity and configured to drive the rotary wheel hub. The battery and control unit is received in the accommodating cavity and configured to supply power to the driving motor and control operation of the driving motor. The battery and control unit comprising an embedded power supply to supply the power to the driving motor.

## Claims

### Claim 1

A remote controller configured to control a vehicle, the vehicle including a pair of front wheels and a pair of rear wheels, at least one pair of the pair of front wheels and the pair of rear wheels being a pair of electric wheels, the pair of electric wheels including a left wheel and a right wheel, each of the pair of electric wheels comprising:
a fixed wheel hub configured to be connected with a shaft of the vehicle;
a rotary wheel hub mounted on the fixed wheel hub, with an accommodating cavity defined therebetween;
a driving motor received in the accommodating cavity and configured to drive the rotary wheel hub; and
a battery and control unit received in the accommodating cavity and configured to supply power to the driving motor and control operation of the driving motor;
wherein the remote controller comprises:
a forward/backward control module configured to control forward movement and backward movement of the electric wheels;
a speed and brake control module configured to control speed and brake of the electric wheels;
a turn control module configured to control turn of the vehicle;
an electronic differential module configured to obtain respective rotation speeds of the left and right wheels through a differential calculation according to control signals from the forward/backward control module, the speed and brake control module and the turn control module, and generate a left wheel instruction for controlling operation of the left wheel of the vehicle and a right wheel instruction for controlling operation of the right wheel of the vehicle; and
a wireless communication module configured to transmit the left wheel instruction and the right wheel instruction to the left wheel and the right wheel of the vehicle, respectively.

### Claim 2 (depends on 1)
